PREIZKUŠANJE TERMIČNE ZMOGLJIVOSTI ELEKTRIČNIH VODNIKOV

Abstract
Diplomsko delo obravnava teoretični in praktični vidik izračuna termične zmogljivosti električnih vodnikov. S poskusi pokažemo zakon o ohranitvi energije, ko se skupna količina energija v izoliranem sistemu ne spreminja. Opisali smo preizkuse toplotne trdnosti električnih vodnikov, ki smo jih izvedli z napravo Omicron CPC 100. Naprava CPC 100 meri tok, napetost in upornost skozi čas. Teoretični izračuni so narejeni po CIGRE metodi. Rezultate dobljene pri praktičnih poskusih primerjamo s teoretično izračunanimi vrednostmi in preverimo kakšna je razlika oz. odstopanje med njimi.

Language: English Testing the thermal capability of electric wires The thesis focuses on theoretical and practical calculation of thermal capacity for certain electrical conductors. With experiments we show the law of conservation of energy, which states that the total energy in the isolated system is constant. We described the tests for thermal strength of electric wires, that were tested with the device Omicron CPC 100. The device CPC 100 measures the change in current, voltage and resistance over time. We use CIGRE method to make theoretical calculations. We compare the results obtained from practical experiments with theoretically calculated values and we try to find the difference or the deviation between them.
